English Abstract
The present study is to investigate the behavior of sand columns and sand columns stabilized with lime to improve so^ soil in curing period seven and twenty eight days.
Three types of lime were used to stabilize sand column.
The three types are lime I (Iranian lime), lime II (Turkish lime) and lime III (Turkish lime expose to heat at 512oC).
The well graded sand was used in this study.
A total number of 38 model tests were classi^ed into three main categories.
The first was performed on saturated soft bed of clay without any treatment.
The second category was carried out on soil reinforced with sand columns.
The third set consists of model tests performed on soil reinforced with sand columns stabilized with lime, this category is divided into three groups, the first consists of model tests tested after seven days, the second tested after twenty eight-day curing, and the third covers model tests of end bearing type stabilized columns tested a^er seven-day curing.
Sand columns stabilized with 11% lime III (floating type) provided highest degree of bearing improvement ratio of 2.91 after seven days curing and 4.1 after twenty eight-day curing, and the lowest degree of settlement reduction ratio of 0.09 a^er seven and twenty eight-day curing.
Sand columns stabilized with لل% lime III (end bearing type) provided a bearing improvement ratio of 3.33 and settlement reduction ratio of 0.086 after seven-day curing.
Thus it is advisable to use lime III to improve the performance of both floating and end bearing sand columns.
